the voltage across a discharging capacitor is v(t) = 10(1− e^-0.2t) generate a table of voltage, v(t) , versus time, t, for t = 0 to 50 seconds with increment of 5 s

Hi. From the question, you were given the time from 0 to 50 seconds and increment of 5. So, the time will be 0, 5, 10, 15, 20......50secs, and for each instance of time, v(t) will be generated by inserting the value of t in the given equation.
Then, you'll tabulate your result as required.
I hope this is helpful.
Cheers!

possibiliterian:

Do you need a computer program to output the result ?

Just in case you needed the a program to solve it, here is a code I just whipped up in Java:

public class CapacitorDischarge {

    public static void main(String[] args) {
        String head = String.format("%-10s|%20s" , "Time(t)", "Voltage(v)" );
        System.out.println(head);
        System.out.println(new String(new char[head.length()]).replace("\0", "-" ));
        for(int t=0; t <= 50; t+=5){
            double v = 10*(1 - Math.pow(2.718281828459045,(-0.2*t)));
            System.out.println(String.format("%-10s|%20s" , t, v ));
        }
    } 
}

An this is what the output looks like:

Time(t)   |          Voltage(v)
-------------------------------
0         |                 0.0
5         |   6.321205588285577

25        |   9.932620530009146

50        |   9.999546000702376

Disclaimer I can't assure you that the result is correct cause the value of e (Euler's number) used was to ten places. The plan is to give you an idea on how to go about it.

Thanks Guys.....Have gotten it
